Piston Ring Pliers, 40-100mm Capacity

Overview

This is a purpose-built hand tool for rapid piston ring installation and removal in engine rebuild operations. The self-adjusting spring tension mechanism automatically compensates for ring diameter variations within the 40-100mm range, eliminating the need for manual adjustment between applications. The nickel-plated steel construction resists corrosion in workshop environments, while the PVC-coated handles provide secure grip and comfort during repetitive work. For shops working with larger displacement engines or requiring a wider capacity range, larger piston ring pliers are also available.

Key Features

• Self-Adjusting Spring Tension: Automatically adapts to ring diameters from 40-100mm without manual recalibration
• Nickel-Plated Steel Construction: Corrosion-resistant, durable metal components suitable for demanding workshop use
• PVC-Coated Handles: Ergonomic grip reduces hand fatigue during extended assembly work
• U-Shaped Jaw Design: Inward-facing hooked ends securely grip or expand rings without slipping
• Lightweight Operation: Minimal mechanical effort required compared to manual expansion methods
• Reversible Function: Can expand rings for installation or compress rings for removal

Business Advantages for Resellers

• High-Frequency Tool: Essential stock item for any shop performing engine rebuilds, overhauls, or piston replacement
• Repeatable Revenue: Mechanics buy once and retain; replacement demand comes primarily from tool loss or damage
• Complements Existing Inventory: Pairs naturally with piston ring compressor tools and other engine service equipment
• Professional Standard: Expected equipment in any serious engine work environment; absence from your catalog creates customer friction
• Profitable Margin: Modest retail price point with strong wholesale discounts encourages bulk purchasing
